Many of the dates of this time are unreliable and the list contains substantial gaps. The genealogy of the Kings has been largely lost: some of those listed are known only from charters, and some may have been sub-kings of the Haestingas (within present-day East Sussex).
The names are given in modern English form followed by the names and titles (as far as is known) in contemporary Anglo-Saxon English and Latin, being the prevalent/('official') languages of the time.
This was a time when spellings varied widely, even within a document. A number of variations of the details below exist. Amongst these are the preference between þ and ð (hard and soft 'th').
